Kill Hannah would be cool. I only have their first LP, but I like it a lot. Haven't listened to it in ages, though.

Dommin is always more than welcome, of course. They're fantastic live performers, and the fact that they're good friends with TBM makes them a great touring partner. I think most of us agree on that, though

I think a really cool tour of nothing but synthy stuff would be TBM, VNV Nation, Kill Hannah and Ladytron. HORSE the band and Enter Shikari are personal favorites, as well, so I personally would be ecstatic at the chance to see them all together, but I don't think hardcore bands like them would be best suited for a TBM tour.
